Default Separate receiving antennae?

This is something that Spike has recommended, so perhaps a
couple of loops at the bottom of the garden well away from
the noise-inducing consumer electronics in this row of houses.

When I, with the right moral fibre to get something that
I wanted, took the Morse test at Portishead (Highbridge)
Radio in 1983, and then had a guided tour of the station,
the operators had a 32-position rotary switch to select
one of many receiving aerials pointed to all corners
of the globe.

I wonder if these would have been Wullenwebers / Elephant Cages,
or somewhere a field of rhombics.

What's the recommendation for remote RX antennae, loops or a single whip?

I prefer 14 element yagi's.

We don't have the open prairie as in Yankland. Here in Britland all
land is owned by somebody and usually parcelled out in small lots,
about the size of a Yank double garage.

Actually in Brit, all land is owned by the cancer of the crown and
those who think that they are homeowners only hold the property
"in fee simple".


Not sure what all the babble about land in the UK is about since a 14
element yagi is 5 meters long.

I haven't used the DX Engineering array antenna, but it might be worth
investigating:

https://stationproject.blog/2013/05/13/receive-antenna-for-the-low-bands-part-1-element-layout-and-installation/
https://patents.google.com/patent/US7423588
Only $3,145.55 plus tax and shipping.

Why a whip?
Why not something fully directional?
Since you are a pi fan like me have a look on google for a pi controlled
direction antenna. Many use old astronomy mounts and while these are
actually for telescopes they also work for a well-balanced yagi or
similar. My wife is an astronomer and has a number of steerable
telescopes I do the building of the computer interface for her.
You can pick up old rs232 controlled mounts cheaply on gumtree.

https://www.raspberrypi.org/blog/con...d-mathematica/

https://www.mups.co.uk/project/software/astrocat/

There are a number of papers in the IEEE Antenna and Propagation Society
library on using a pi to control directional antennas, if you are member
of the IEEE or qualifying society then you will have free access.

No entirely correct.
This applies under English law only so applies only to England (and
probably Wales) and not to the whole of 'Brit'; Scotland and NI have
their own legal systems.
Scotland abolished all feu duty and feudal tenure (Scottish equivalent
of fee). NI used to have a similar system called 'Udal' but that has
been abolished.

Only????? :-)

I was thinking in terms of bits from the junk box
with additional expenditure of only tuppence ha'penny.

But thanks, anyway.

Andy, you're mistaken; Gareth's a pie fan.

Y'er welcome. However all is not lost. If you search for "Antennas
made from junk", there are a few that look like they might meet your
cost and construction requirements:
https://www.google.com/search?q=antennas+made+from+junk
Please note that it is not necessary to start with junk in order to
produce an antenna that might be declared to be junk. This is not
really a bad thing, as it is well known that ugly antennas work best,
and that nicely constructed antennas rarely work without the addition
of decorative junk.
